As you can see from the above example, Larry has created three profit centers that multiply his income far beyond what he earns from the initial sales of his book:

Lesson 1: Yearly update. Each year, Larry publishes a yearly update of trends that have been assembled from reports from piano technicians and tuners around the country. His yearly updates discuss trends in pricing, frequency of repairs, and other news about piano manufacturers. His yearly update is now an e-book, although a printed form is also available.

New Piano Pricing Guide Service. Once you have narrowed your choices to a few makes and models, Larry can provide you with insider information about the range of prices for specific pianos in your area, eliminating the possibility of paying too much.

Piano Purchase Consulting Service. Larry is also available for 30-minute, scheduled telephone consultations with customers concerned about paying too much for their pianos. He can help you create a pricing strategy for your shopping, so you can drive the best deal possible.

As successful authors recognize, writing is an entrepreneurial business. Authors must build businesses around the credibility, opportunities, and visibility their books create for them.
